but there's an Irish jockey called RubyWalsh who's pretty well known in the UK and Ireland at least. His full name's Rupert but he goes by Ruby professionally. So if anyone questions him, he's got a male Ruby to cite.

No. Does anyone remember middle or high school? I recall it being a brutal time for fragile, developing egos. Being a boy with a girls nn would be horrible. Ruby isn't unisex anymore, and it's a popular girls name. Why not Roo/ Rue? That's an acceptable, cute nn for a boy.
